like “samarium- cobalt” are used, such magnets
can really be used in dynamic conditions of shaft
loads in motor transport up to 200 kW of
mechanical capacity.
Magnetic Reducers
Modern multi-stage reducers are applied
everywhere, in many fields of technique,
ranging from motor transport to kitchen units.
Meanwhile they are rather complicated and
expensive mechanical devices. Up-to-date
constant magnets and their force interaction
enable us to create a totally new energy saving
type of non-contact new generation reducer. Let
us consider them.
The fundamental property and condition of
force interaction of one/ many magnetized
bodies (e.g., constant magnets) is their tendency
to be drawn by antipoles and their tendency to
mutual immobility of their poles in space.
Reduction of speed of two magnets with
different poles, controlling and controlled, is a
consequence of this effect. To prove this fact one
should assembly a simple magnetomechanic
plant, shown in Fig.2.
Fig. 2. Magnetic reduction of speed effect
When the elementary magnetic bar 1 is rotated,
the angular velocity of compound magnet 2, 3
rotation is twice as smaller as magnet 1 rotation
speed, as only in this case the magnetic fields of
these unbound magnets are mutually immobile in
space. Yet this device is a simplest magnetic
reducer of speed.
Dudyshev’s Magnetic Disk Reducer
Fig. 3 illustrates a more effective magnetic disk
reducer designed for a non-contact transmission
of considerable turning moment from drive shaft
to driven shaft:

It consists of 2 parallel disks 1 and 2, fabricated
from any non-magnetic material, working
potent constant magnets 3 and 4, installed on
these disks with their antipoles towards each
other. The speed reduction ratio of the drive and
the driven shafts 5 and 6 of the non-contact
reducer is set in the ratio of the number of
magnets on the disks. Due to minimal working
clearances between the working magnets, this
device can be applied in non-contact power gear
boxes in motor transport of new generation on
in other devices.
Besides, the performance index of such a
magnetic reducer practically equals 1. Even now
it’s possible to create compact non-contact
magnetic reducers, capacity ranging from
hundreds of W to 60 kW, as the force of
attractive interaction of up-to-date magnets
made of alloys like “samarium- cobalt” within a
split millimeter reaches thousands of newtons.
With further developed magnetic materials and
constant magnets a magnetic reducer can
transfer up to 100- 150 kW of mechanical power.
